Engine T-Motor MN4004

Buy T-MOTOR MN4004 300KV brushless motor for powerful and efficient multi-rotor systems

The T-MOTOR MN4004 300KV motor from the Antigravity series is a highly efficient brushless motor designed for professional multicopters and drones, where every gram of weight and watt of power is critical. Thanks to its ultra-thin design and sophisticated cooling system, this engine provides outstanding thrust with minimal power consumption. It is ideal for long autonomous flights, aerial photography and other tasks requiring high reliability and efficiency..

• High efficiency thanks to single thick copper wire winding.
• Ultra-light weight of only 53 grams to reduce drone weight.
• Unique cooling system for stable operation under load.
• Quality EZO bearings for long service life.
• Low no-load current of only 0.2A to save energy.

How the T-MOTOR MN4004 300KV engine works

This is a brushless motor with an external rotor (outrunner). When voltage is applied to the stator windings, a rotating magnetic field is created, which drags the rotor with permanent magnets along with it. A KV value of 300 means that the motor rotates 300 times for every volt of voltage.

The absence of brushes ensures high reliability, low noise levels and minimal wear. A special design with one thick copper wire reduces energy loss due to heating, and a unique ventilation system effectively removes heat, allowing the motor to operate stably at high speeds.

Specifications

Model MN4004 300KV has dimensions Φ44.35×19mm and weight 53g. Rated voltage is 4-6S LiPo. No-load current at 22 V is 0.2 A. Internal resistance - 452 mOhm. Peak current (180 s) reaches 9 A, and maximum power (180 s) reaches 216 W. Winding configuration - 18N24P. Wire length is 50 mm, shaft diameter is 5 mm. It is recommended to replace bearings every 60 hours of flight to maintain reliability..
